Prior this commit the ami image type produced raw.xz images. This was bad for
two reasons:
- The upload was broken because AWS doesn't support tar.xz format
- XZ compression is terribly slow
This commit changes the format to vhdx, which is supported by AWS and also
quite quick. See https://github.com/osbuild/osbuild-composer/issues/257
why vhdx was chosen.
Fixes#257
We need to make partition uuids stable to be able to run image-info
tests on images using gpt. For example all aarch64 images use gpt.
Also change the type of the (part) UUID to string because that's what
the other UUIDs use and it is easier to work with.
There is no point in having the grub2 stage in pipelines for image types
that are not bootable. The current version is probably a result of
previous refactoring where the member variable was named `IncludeFSTab`.
Moving the grub2 stage into the conditional branch should also fix test
generation on aarch64.
Finally it is necessary to regenerate test cases for non-bootable image
types.
This change makes the dracut-config-generic installation in par with
Fedora. Also, by having it in bootloader packages, it is not installed in
non-bootable images, where it provides no value.
Dracut is unfortunately very host-dependant by default. The package
dracut-config-generic forces it use a generic configuration instead of a
configuration generated from the host environment.
This change should make the image generation more reproducible. For example
it was not possible to boot ami images built on Travis on AWS prior this
commit.
Also, the tests were re-generated in this commit.
In PR#395 we discussed the spelling of archs vs. arches and we agreed to
use arches. This patch only renames the public method `ListArchs`in the
`Distro` interface.
This means that the unit tests no longer need to load the
repositories from the git repo, and in a follow-up, osbuild-composer
won't need to either.
By splitting the repositories used for testing from the system
repositories available through the weldr API we are able to extend
the system repositories without affecting the reproducibility of
the tests.

The main reason here is not to make sure we have the right set of build
packages, but rather to make sure the pointer hierarchy (distro->arch->
image type) works as expected.
This patch uses the same approach as fedora31 few commits ago. It moves
the arch pointer to the imageType struct and sets it while creating the
distro->arch->image type hierarchy in the setImageType function. The
rest of the patch is just renaming.
It uses the same approach as fedora31 few commits ago. The pointer to
distro is moved to "arch" and "arch" now contains a map of allowed
image types for each arch.
Also include setArches and setImageTypes helper functions to ease the
creation of pointers from the structures to a parent structure while
creating the distro->arches->image types hierarchy.
Previously we had to type the name of the architecture and image type
multiple times (in the definition, when inserting it into each parent
structure etc.) and it would get even worse because we would have to do
the same for all distros. These helper functions make it less error
prone by copying the name in the function automatically.
The former one was just a wrapper to the second one. In this patch I
removed the fedora31ImageType struct and instead moved the pointer to
the imageType struct. The previous solution always created a new wrapper
and returned it to the called. This new solution creates a shallow copy
of imageType, assignes arch field, and then returns the result to the
caller. It should achieve the same without the additional wrapper.
This information is now provided only when an architecture is specified,
so it is necessary to first obtain object implementing the Arch interface
then object implementing the ImageType interface and then you can get
the filename and mime type.
Tests are changed accordingly to the new API.
xz compression is used for the ami and tar output types, it should be in
the buildroot. This fixes Weldr integration test (/cmd/osbuild-tests) on
ARM architecture (aarch64).
The fact that it worked on x86_64 was just a happy coincidence because
we require grub2-pc which in turn requires dracut which requires xz. We
should not rely on these implicit dependencies because we need xz
unconditionaly, therefore adding it to build packages for all platforms.
Delete unused methods and make types and fields private where
possible. Some code is moved around, but apart from that there
is no change in behavior.
The naming of the distros were moved back into the distro
packages as the common types now only had one user, and this
allowed us to drop some redundant error checking.

Usage of these have now been entirely replaced with the newly
introduced interfaces. The individual distros should be cleaned up
and dead code removed, buth that is left for a future patch.

This is purely internal, and there is no benefit to translating
to a tag, a string identifier will do just fine.

Objects implementing these interfaces will represent the
architecture support for a given distro and the image type
support for a given architecture distro combination, respectively.
The idea is to always resolve to these objects early, and drop
the equilavent methods from the distro interface. This means that
we convert our input strings to real objects once, and then never
have to verify their correctness again.

Require the caller to pass in the required distros explicitly. This
would allow us to easily add distros in osbuild-pipeline and tests
before exposing them in composer itself, for instance.
This means there is no longer a dependency from the distro package
to each of the individual distros, so the distros are now able
to depend on the distro packag for types and interfaces.

Simplify the code by dropping the potential error return. The
constructor simply instantiates some maps, this cannot fail.

Mixing the way to build a distribution with where to get the source
packages from is wrong: it breaks pre-release repos, local mirrors, and
other use cases. To accommodate those, we introduced
`/etc/osbuild-composer/repositories`.
However, that doesn't work for the RCM API, which receives repository
URLs to use from outside requests. This API has been wrongly using the
`additionalRepos` parameter to inject those repos. That's broken,
because the resulting manifests contained both the installed repos and
the repos from the request.
To fix this, stop exposing repositories from the distros, but require
passing them on every call to `Manifest()`. This makes `additionalRepos`
redundant.
Fixes#341
This makes two changes simultaneously, to avoid too much churn:
- move accessors from being on the blueprint struct to the
customizations struct, and
- pass the customizations struct rather than the whole blueprint
as argumnet to distro.Manifest().
@larskarlitski pointed out in a previous review that it feels
redundant to pass the whole blueprint as well as the list of
packages to the Manifest funciton. Indeed it is, so this
simplifies things a bit.

This was never actually used anywhere, as passing it to dnf-json
was a noop.
We may want to reconsider the concept of a source/repo name and
how it differs from an ID, but for now drop the name.

Conceptually, we used to insert the high-level packages and package
groups into the pipeline together with the expected repository
metadata checksum.
osbuild, using the dnf stage, would then fetch the metadata, verify
that its checksum is correct, compute the dependencies, and install
the packages.
Among the problems this has is that it made it impossible to cache
and share the resolved metadata as well as the rpms. Moreover,
as the checksum was at the repository-level, rather than at the
package level, it meant that we would refuse to build a pipeline
as soon as there were any changes at all to the repository, as we
could no longer guarantee the installed packages would be the same.
As of this patch, all repository and metadata handling is done by
composer, rather than osbuild. This means that the resolved metadata
can be cached between runs, which and it means that we can now
pin individual packages, rather than the entire repository. Meaning,
that as long as the rpms are still available, we are able to build
a pipeline.
The downloading of rpms is now done by a source helper in osbuild,
which means that they can be cached and shared between runs too.
One consequence of this change is that we resolve the location of
each rpm in composer, and pass that to the worker. As the worker
may not be in the same location, we do not want to use metalinks
in composer for this, as it would pin the repository closest to
composer, rather than the runner. Instead, we now manually select
a baseurl for each repository, which should be generally the
most useful one. Fedora helpfully provides such baseurls, so
this should work ok.
The most important thing to verify when checking this commit, is
that the image info in our test-cases remains unchanged.

This gives us more readable output. Both because it gives just a
diff, rather than the whole object as a string, but also as it
captures differences between the objects that thir string
representation does not.
In particular, if a field is an interface I, and T implements I,
then an object of type T and a pointer to the same object can both
be assigned to a variable of type I. Either way, the JSON
representation is the same, but the objects (correctly) do not
compare equal.
This is a pain to debug.

A manifest is struct made up of a pipeline and a sources object. So
far all our sources objects are empty, but we have moved from
using pipelines to manifests everywhere, in preparation for
generating pipelines that require sources.
Make the same change in the test cases.
